Which of the following is an example of a bacterium pathogen?

Explanation:
Salmonella is a bacterium, a single‑celled prokaryote that can cause illness in humans. As a bacterial pathogen, it infects through contaminated food or water and can lead to gastroenteritis and sometimes more serious disease. The other organisms are not bacteria: influenza is a virus, Candida is a fungus, and Plasmodium is a protozoan parasite. Recognizing that Salmonella is a bacterium helps explain why antibiotics, which target bacteria, are used in bacterial infections, whereas antivirals, antifungals, or antiparasitics would be used for the others.
